Insider Threat
Threat IntelligenceDefinition
Security risks from employees/contractors mishandling data.
Technical Details
An insider threat refers to security risks that originate from individuals within an organization, such as employees, contractors, or business partners, who have inside information concerning the organization's security practices, data, and computer systems. These threats can manifest in various forms, including deliberate actions (malicious insiders) or unintentional actions (negligent insiders). Technical measures to mitigate insider threats include user behavior analytics (UBA), access control mechanisms, data loss prevention (DLP) tools, and monitoring solutions to detect unusual activities that may indicate a potential insider threat.
Practical Usage
Organizations implement insider threat programs that involve training, monitoring, and policy enforcement to address the risks. Real-world applications include establishing clear data handling protocols, conducting regular employee training on security awareness, and using technological tools that track user activity and enforce least privilege access. Additionally, organizations may conduct background checks during hiring processes to identify potential risks before onboarding new employees.
Examples
- An employee intentionally leaking sensitive customer information to a competitor for monetary gain.
- A contractor inadvertently sending confidential data to the wrong email address due to lack of awareness about data handling policies.
- An employee accessing sensitive files that are not relevant to their job role, which raises red flags in user behavior analytics.
